[21.04] Trying to Get Ready: Blazars, Pulsars and Unidentified Sources in the GLAST Sky

R.W. Romani (Stanford U.)

EGRET gave us a first look at the Gamma-ray sky, but
starting in 2007 we expect that this window on the
non-thermal universe will be thrown wide open with GLAST.
One key lesson from EGRET is that will we need coordinated
multi-wavelength efforts from the wider astrophysics
community to make sense of the GLAST observations. As the
first sky survey data come in, we will want to identify many
more sources from the known blazar and pulsar classes and to
start to constrain novel types of objects. I describe here
some of the preparatory work that is being done to get ready
for this phase. Much of the work starts from radio surveys,
helping us zero in on non-thermal phenomena. By identifying
candidate gamma-ray blazars and radio pulsars we hope to be
ready to interpret much of the GLAST sky. Of course
understanding of the source physics requires focused
campaigns on bright sources and I note a few non-thermal
radio/X-ray studies that can advance this work. I conclude
by discussing briefly the sorts of supporting data that will
let us chase down the GLAST survey sources that won't yield
to easy identification, and should lead to the pay-off of
new and exotic object classes.
